Applications & selection
Typical uses
- High pressure pumps
- High temperature service
Industries: Petrochemical, Power, Steel.
Selecting the right construction
Specify shaft speed, pressure, temperature and extrusion gap. Review aramid-corner construction for the medium and mating-surface condition.
Chemical resistance depends on the polymer, fillers, inserts and process conditions. Confirm the exact medium and concentration; general PTFE properties do not establish a complete assembly's service rating.
